Experimental Study of Vertical Fire Spread of Exterior Wall Finishing Materials

Abstract

In this study, we have analyzed the full scale fire test from the fire accidents of finishing materials on the external wall of the buildings, and conducted the vertical fire experiment of finishing materials on the external wall of the buildings. As the ISO 13785-2 fire test, a international test standard, has been judged to be most appropriate as the test method that could figure out the fire performance of finishing materials on the external wall with the effect of external flame break-out due to the fire in the unit compartment among the real scale fire test methods, we have built up the experimental equipment for the full scale vertical fire experiment of finishing materials on the external wall of the buildings. As a result of the full scale vertical fire experiment, the fire has been spreaded up to 4m upwards within about 2 minutes at the point of 5 minutes when the external flame break-out was at maximum. The temperature was recorded as 897.7-987.7 o C, and the test result showed that general aluminum composite panel was vulnerable against spread of the vertical fire on the openings due to external flame break-out.
